SednaEarfit XELASTEC 2

These stay in much better than original WF-1000XM5 ear tips that would start to slip out after a while. Sizing is also accurate; I used S size in original, and S was also the best size xelastec out of the three I got (SS/S/MS).

Sound quality was pretty bad with my Sony WF-1000XM5 compared to the stock tips and the SednaEarfit foamax.

it doesn't irritate my ear canal, compared to wf1000xm5's foam eartips, and the stick makes it sit better

Makes the MEST MK2 god like, no other tips even come close to that combo.

Absolutely incredible. These are THE ONLY ear tips, that fit my 7Hz Timeless IEM and my ears, stay secure as NONE other AND make them sound better (and best).

I've tried on them (7Hz) a few other brands, like a few spinfits, Comply Foam (which work great for me but not for the IEM) and none were able to have the IEMs sit anything close to that stable.

They are so great that I order them from basically other side of the world consistently.

The customer support is also incredible. Once my package got lost or something by the delivery company and they sent a new pair for free. Really one of the few brands with excellent product and well as all the other aspects. Will definitely remain a long term client.

Strongly recommend!
